SparkFun Current Sensor Breakout - INA169 Current, Sparkfun Originals Sound The optional add-on sensors attachThe INA169 is a ? high side current monitor,? which means that you place a resistor (a ? shunt resistor?) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a resistor from the output of the INA169 to ground, you can measure the voltage at the output. Input common mode and power supply voltages are independent and can range from
